Automatic Ai Noise Canceling Function - Sony MDR-NC300D Product Information

2-3 Automatic AI Noise Canceling Function
The characteristics of ambient noise vary depending on the situation. For example, the characteristics of ambient noise on a plane,
on a bus or a train, or in an office environment are different.
The AI Noise Analyzer inside the processor constantly monitors and analyzes the ambient noise. This function selects in real time
the most appropriate of the noise canceling modes provided by the headphones (Mode A: low to midrange frequency NC, Mode B:
ultra-low frequency NC, Mode C: wideband NC). In other words, it selects the mode that minimizes noise at the eardrum.
This advanced software function enables users to enjoy the optimum noise canceling effect automatically in any noise
environment.
Typically, "Mode A: low to midrange frequency NC" effectively reduces the noise present mainly on a plane; "Mode B:
Tips
ultra-low frequency NC" effectively reduces the noise present mainly on a bus or train; and "Mode C: wideband NC"
effectively reduces the noise present mainly in an office environment (OA equipment, air conditioning, etc.).
The AI Noise Analyzer analyzes the actual ambient noise in the user's environment and selects the most effective noise
canceling mode.
